So just switched out my Maximus VI Formula & 4770K for a Maximus VIII Formula & 6700K along with a Samsung 950 Pro 512GB M.2 drive.

Load times seem right at or slower then the Corsair Neutron GTX drive the 950 replaced. Reading around it seems having CSM enabled can cause a slower then should be boot time when using a m.2 drive.

Problem is if I disable it then the computer won't boot stating my VGA isn't compatible with UEFI. :-( Anyone else have this issue and a work around possibly?

Been waiting for the 1080 FTW/Classified cards to come in stock along with waiting to hear factual info on the high end AMD offering including benchmarks/pricing. This problem will eventually be solved with a new GPU but still on the fence until more information comes from AMD before I pull the trigger on nvidia for once in a very very long time. (9800 GTX days)
